UV WEB OFFSET PRESSES -- Finding the Cure

The critical features needed for a UV application is the ability to run at press speeds with consistent quality. This is achieved through the design of inking systems that are compatible with the higher tack of UV inks. Over certain speeds, generally defined as 800+ fpm, chilling of vibrator rollers is a necessity. Chilling of fountain solution is also a plus, giving a more stable environment in which to print, according to Fetherman.
